Could not find type 'OxyPlot.WindowsForms.PlotView'

[issaksdu44]

Platform and tools

• Sharpdevelop 5.1.0.5134
• .NET 4.5.51209
• Windows.Forms
• OxyPlot.Core.1.0.0-unstable1870
• OxyPlot.WindowsForms.1.0.0-unstable1870

Issue description

At first, everything was fine, no warnings and the designer shows the form correctly and I can easily add components.

After that I added OxyPlot correctly from the Package Management Console and I found the new PlotView component in the Custom Comonents tab.

The problem is that I can't add the component to the Form from the tools tab, so I did it by writing the equivalents statements in the source file.

The building process went fine and the application worked fine, but now I can't see the Form in the designer tab and instead I got this message:

Failed to load designer. Check the source code for syntax errors and check if all references are available.

The sample shows up without any errors in VS2015.
So this might be a SharpDevelop issue?

[objorke]

could this be a PCL-related issue similar to what we had for the wpf designer?

[issaksdu44]

@tibel Obviously it looks a SharpDevelop issue.

@objorke I really don't know

I tried something and the result was more or less better.
I moved the declaration of the plotview component from MainForm.Designer.cs to MainForm.cs and now I can see the form in the designer but I can't add the component from the tool list (the plotview is there).

Any clues ??

Here is the solution

copy the OxyPlot.dll and OxyPlot.WindowsForms.dll files into C:\Program Files (x86)\SharpDevelop\5.1\bin, then restart SharpDevelop
